Translation of abstract (English)

The use of a tactile channel instead of a visual one, is an alternative help for blind or visual impaired people to find their way through the seeing world. In this work the basics are set for a system which could enable it. In order to do so, a pneumatic operating display has been built. It can be controlled by a computer tuner, so that automatic experiments, with different strength of impulses are possible. The subject lies in a fMRI and recieves the impulses, at the same time as the fMRI measures the brain activation. These scans made to locate and quantify the impulses controlled by the trigger, serve to estimate the chance in such a test.
